Title: Allow multiple identifiers in OvProductType and OvagentType and allow multiple TEL values in OvcontactType

The same element TEL is used for 'telefoon', 'fax' and 'mobiel' and multiple values of each are allowed according to the specs.

from the v1.0 specs:
"Telefoon, Mobiel en Fax zijn niet verplichte attributen die meerdere keren mogen voorkomen."
